Blazor Pager Accessibility
Out of the box, the Telerik UI for Blazor Pager provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The Pager is compliant with the Web Content Accessibility Guidelines (WCAG) 2.1 AA standards](https://www.w3.org/TR/WCAG21/) and Section 508 requirements, follows the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) best practices for implementing the keyboard navigation for its component role, provides options for managing its focus and is tested against the most popular screen readers.
WAI-ARIA
This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.
The PageSize select must be implemented either as a DropDownList component with no filtering or through a native <select> element.
